x86, msr: Have the _safe MSR functions return -EIO, not -EFAULT
For some reason, the _safe MSR functions returned -EFAULT, not -EIO. However, the only user which cares about the return code as anything other than a boolean is the MSR driver, which wants -EIO. Change it to -EIO across the board. Signed-off-by: H.
